Re: T470 bios needed
I got my t470 20HE corrupted in a bad flash (no boot).
The winbond is a 25Q80JV 8Mb chip, but all I see here is 16Mb files for this bios.
I used Neo programmer and a ch341 to read the bios.
Am i missing something?
is there a way to extract a bin file from a bios update?Attached Files

Re: T470 bios needed
I found an other one ; 25Q128FVSQ
seems to be the right size, but the read freezes (neo 2.2.0.10)
Current programmer: CH341 Black
SPI ID: EF4018
---------------------------------------------------------------------------
Currently selected: W25Q128FV [3.3V] 128 Mbits, 16 Mbytes
---------------------------------------------------------------------------
i'm reading on board, the chip gets detected

I don't understand why rookies likes him the most, probably because of the number 80 on the marking.

Edit:
Yes it is, that's the right one. Are you using a clip to read the chip?
.
Freezes sometimes in the beginning, sometimes halfway.
desolder?

Maybe it's time to put in my signature - "Do not touch the 25Q80xxxx chip"
